meow-MOLD.

Specification of Letters' Patent.

Application led September 9, 1913. Serial No. 788,882.

To all whom it may concern:

Be it known that I, CHARLES W. LUMMis,

a' citizen of the United States, residing at `Worcester, in the countyof Worcester land Commonwealth of Massachusetts, have invented a new anduseful Improvement in Ingot-Molds, of which the following, to-

getherwith the accompanying drawing, 1s

' y. ings have setA to allow them to be taken out Y permanent `moldshave set, the plugs may be removed andv to provide a perm of the molds.In some cases permanent molds have been used, the bottoms of theseplugged openings so that, after the castings the castings pushed outthrough the 'tops of the molds. This i's an undesirable construction asit is difficult to make the plugs fit properly, the resultV b/eing thatfins are formed on the bottoms of the castings so`as to cause them tobind in the molds and make them difficult, to remove. It is desirable topour the castings or ingots in permanent ,cav1t1es'4 and 5. Theloweredges of the side 'walls of the strainer fit closely againstl molds inorder to save the labor of dismanl tling and reassembling the moldsafter each pouring.

One object of this invention, therefore, is

lanent ingot mold so constructed that the ingots may be removedtherefrom withoutv opening or dismantling lany part of the mold.

In order tosave time, labor and space, it

"is also desirable to pour a plurality of the simultaneously, andanother Aobject ingots t to provideV an improved of the invention isform of ingot mold which will permit thisV to be done. The form .of moldto be described. hereafter vas illustrating the inventionis designed forthe simultaneous'pouring of two ingotsgkit is apparent, however,

being provided with that by increasing the number of ingot cav' ities inthe mold, the number of ingots'whichmay be poured simultaneously will becorrespondingly increased.

Other objects and advantages will appear from the following descriptiontaken in connectlon with the accomp' ying drawing, in which- Figure lisan elevation of an ingot mold with 1ts. strainer constructed inaccordance with my invention; Fig. 2 is a plan view of the mold andstrainer shown in Fig. l; Fig. 3 is a vertical sectional view on 1theline 3.-?, of Fig. 2; Fig. 4 is a vertical sectional view of thestrainer and the upper extremity of the mold on the line 4-4 yof Fig. 2;and vFig. 5 1s a hor1zontal sectional view on the Patented Aug. 1,1916.

gether. A bottom plate 8 is fastened against the lower ends'o'f thesections 1, 2 and 3 by screwsv 9, this bottom plate serving to close thelower ends of the cavities -4 and 5.

-Strengthening ribs 10 are vformed' on the outer facesof the outerlsections land 2.

A strainer 11 rests upon the top of the sectionsA '1, 2 and 3 of themold for the purpose iwf-directing the molten metal into the the tops ofthe sections 1, 2 and 3 andthe walls are solid or imperforate toobstruct the escape of molten metal over the outer edges of the mold andaway from the ingot A horihas a number of Vopenings-14: located abovethe cavities 4 and-5 for directing the molten metal into these cavitie'sPins 15 serve t0 position the strainer properly upon the sections 1, 2and 3 vofthe-mold The ingots 16 are formed by pouring molten metal intothe strainer 11, the metal flowa space'common t0 the upper ends of allofl said cavities, whereby the overflow Athere:- from may be renderedavailable as a hold for withdrawing the ingotsfrom .the cavii ties. Y

7 Thecoinbinatio'n with an ingotmold lproviding a plurality of ingotcavities, of a metal delivering memberl spaced above and common to allof said cavities, and means vides a hold for pulling said ingots f1om'tlie cavities.

9. An ingot mold providing `a plurality of permanent ingotcavitieshaving contracted` lower ends, and removable means surrounding the upperends of sald cavities tor forming a hold by which the ingots may bewithdrawn simultaneously from said cavities.

10. An ingot mold providing a plurality of permanent ingot cavities, achamber commonto the upper endof allef said. cavities in which theoverflow metal therefrom is confined, andl removable means adapted toVexpose the metal constituting such overflow,

whereby the latter is rendered available as a hold for simultaneouslywithdrawing all the ingots from said cavities.

11;-A The combination with an' ingot mold providing a plurality of ingotcavities, of a metal delivering member spaced above and common to all ofsaid cavities, having delivery openings directly above each cavity,

and the tops of said cavities for confining the overflow metaltherefrom.
